I was thinking of trying this software, but its unclear why the server is limited to 1 user, and if that one user has to be on the server machine – what if you have 5 computers? What happens if you don’t log out from one machine before you try to log into another?

you can create Users, search in forum is easy.
If i remember is.
Creat a new Fragment with Title #UserName and tag #User
and next save and creat all user with a new fragments
Title #MyName and tag #User
good luck
